yes something similar,

this one: 
http://blog.tynemouthsoftware.co.uk/2015/10/which-pets-support-which-pet-microsd.html

(the one installed outside horizontally)


it's brand new I just received it, I guess the problem comes from the 
cbm 8032 board
I'm thinking to a PIA line dead or broken mc3446

I have some spares 6520/6522  I've ordered some 3446

I have a petSD+ but I dont have the cable adapter to connect it


not working with basic 4 commands
same result with basic 2 commands
